Question

A sample of oxygen gas at a pressure of 0.656 atm and a temperature of 27.2 °C, occupies a volume of 10.7 liters. If the gas is allowed to expand at constant temperature to a volume of 13.1 liters, the pressure of the gas sample will be ______ atm.

Fill in the blank.

Answer 1

The correct answer is 0.536 atm.

Step-by-step explanation:

The formula to use to solve the given question is,

P1V1 = P2V2

Based on the given information, the initial pressure (P1) of the oxygen gas is 0.656 atm, the initial volume (V1) is 10.7 L. The new volume (V2) given is 13.1 L, there is a need to find the new pressure of the gas (P2).

Now putting the values in the above equation we get,

0.656 atm * 10.7 L = P2 * 13.1 L

P2 = 0.656 atm*10.7 L/13.1 L

P2 = 0.536 atm
